To all whom it may concern:

Be it known that I, GEORGE PALMER BAILEY, a citizen of the United States, residing in the city and county of Ihiladelphia, State of Pennsylvania, have invented a new and useful Dough-Molding'Machme, of which the following is a specification.

This invention relates to a new and useful dough molding machine, and more particularly to a mechanism for working and forming a mass of dough into a certam shape or conformation whereby. it is made ready for the baking process, and when d1scharged from the machine is in the desired shape for the particular .kind of loaf of bread which is to be made.

In the accompanying drawings I have shown a machine particularly adapted for molding dough into a loaf of elongated shape, having reference particularly to the loaf known at the Vienna loaf, although ofcourse it will be understood that I do not wish to be limited to this specifically, as the machine may be readily adapted for molding loaves of a different shape, and I- so contemplate its use in practice.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to -'be understood that the various instrumentalities of which my invention consists can be variously. arranged and organized and that my invention is not.limited to the preelse arrangement 'andlorganization of these instrumentalities' as herein shown and de- Figure 1 represents a sideelevation of a machine 'embodyingmy invention.

- Referring to the drawings :1 designates the main frame of my. novel dough forming reference indicate juncts. Fig. 11 re resents a detail of a-bear Fig. 12 represents a machine upon which is carried 'a rotatable shaft 2 which, in the resent instance, serves as a pivotal sup ort or an auxiliary frame 3. Thi's'latter ame 3 as will be apparent may be moved toward or away from the mam frame 1 as desired and forms a support for certain essential elements, of construction which will later be described in detail.

4. designates the main driven shaft rota.-

tably mounted at a suitable point on the aux iliary frame 3 and carrying a sprocket or the like, by means of which power is transmitted from a suitable source. This'shafi14, in the present instance, has secured thereto a substantially ellipsoidal roll ,6 which is adapted to rotate therewith and serves, in connection with other adjuncts hereinafter described, as a work' roll for forming the dough into a predetermined shape.

7 designatesa second sprocket fixed to the shaft 4 and adapted to transmit motiontherefrom' to a chain 8 which drives a sprocket 9 ona countershaft 10, this latter 5 aft being also mounted for rotation'on the auxiliary frame 3 and lik wis Games a. roll 11 substantially of the sameformj as the roll 6 and serving a like purpose. The count'ershaft 10 in turn transnuts mot-ion through a sprocket 12, chain 13 and sprocket 14 to the shaft'2 which has fixed thereto the I drum 15 and passes loosely through the ears '16 which serve as'apivotal support for the auxrliaryirame 3. 1

'17 designates a belt or bolster which passesabout the drum 15. and also about a second drum .18 rotatably mounted in suitable ex-- tensions or bearin'gsflO of the frame 1. This ass long'i tudmally of a channel 21 forme' by" a bed I m bars 27 carried b g to;

22, side walls 23 and overhangin ways 24' which latter serve'to roperly gui e the belt in its travel, Thebes 22, in-the present in stance, serves as a support or table upon which the dough travels and is fed by the action of the belt.,17. In order-to properlyv support the bed 22, 1 preferably. mount .the same on cross bars 25 adjustably sus ended on stay bolts 26 which pass throng cross I the main frame 1, while adjustment is e ected' by nuts 28 or like devices. .7

'29 designates upper cross bars for joining H the ends of the stay bolts 26 and the same 5; are likewise adjusted 'by' nuts .30. It is preferable 'to proVide' a means for varying at will the depth of the channel to the belt 17, and. for I v in".th'e present instance, employed arotatable 2o stud'31 adapted to be operated by the hand: wheel 32 and passing through a' threaded boss 33 of the ,bar 27, and it will thus be seen that b turning the. said wheel 32 in j the require direction that the bed 22 may '25 be raised or-lowered' as occasion demands, 34' designates. a receiving chute for thedough, preferably fixed to the bed 22' and forming a curved continuation thereof with l side plates 35 and an open end 36: adjacent 30 thebelt17.' "i

1 and of a contour substantially similar I to 8B the curvatureof the roll 11 though. it'will be noted, as shown in Fig. 12, that the said face 38 at its central portion is-spac'ed fa-r then from thesaid roll 11 than atits ends, since it is desirable in this type of machine to form a loaf thicker at the center than at its, ends. This receptacle 37 has each of its sections provided with a projecting flangeor guide 39 which-are adapted for sliding en- 1 gagement with-waysor grooves 40 formedxin the sides of the frame 1,fthe said grooves lie-- ing disposed preferably at an angle of 90 in order that the two.

This spindle 76 is preferably provided with a threaded portion carrying a sleeve 78 integral with which, in the present instance, is a slottedarm 79 engaged by the pin 80 of the third section of the receptacle 57. This latter section of the receptacle 57 is the delivery end of the machine and therefore a receiving table 81 is mounted adjacent thereto and is adapted to receive the formed dough as it comes from the machine. In connection with the receptacles 37 and 57 itwill be noted that the receiving and delivery ends of each of them is provided with a curved ortion 82, in order to facilitate the travel 0 the dough from the bed 22 to one receptacle, from one receptacle to another and from the last receptacle to the receiving table 81.

83 designates a pair of plates pivotally mounted and suitably counterweighted in order to be normally suspended in the path of the dough during its passage through the machine. The function of these plates is to straighten the dough and cause proper delivery of the same to the adjacent receptacle, and it will be noted that one plate 83 is located between the conveyer mechanism and one receptacle, while the other plate 83 is located between the receptacles. In connection with the last named plate 83 attention is directed to the fact that it is so shaped as to substantially conform to the shape of the roll 6, that is, one edge thereof is cut away on a suitable arc.

In order to prevent clogging of the re ceptacles 37 and 57 and avoid sticking of the'dough while passing beneath the rolls 6 and 11, I preferably mount adjacent to and above each roll a-sifter container 84., each of which is fixedly secured to a projecting bracket 85 of the auxiliary frame 3.- These containers are each provided with-a longitudinally disposed opening 86 in the bottom thereof which is covered with a perforated plate or screen 87, which permits the flour or other material to sift through and drop upon the rolls as desired. 'An agitating device is preferably mounted in each con-- trainer 84 and com rises, in the present 1nstance, a rock-sha 88 longitudinally disposed .within each container and carrying thereon a plurality of fingers 89,preferably arranged in staggered relation and adapted to break up the material and maintain it in condition for proper sifting action. The rods 88 are continuously actuated during the operation of. the machine by means of reciprocating crank rods 90 and 91, the latter being connected to a crank pin 92 of a disk 93 on the shaft 2, and the former having secured thereto crank arms 94-. which are fixed to the rock-shafts 88, respectively.

It may be desirable in the use of my'novel forming machine to operate the same in connection with certain types of mixing or molding machines, and for this purpose I provide an attachment device whereby the two machines can be fixedly secured together so that the product of one is delivered directly to the other. This mechanism in the present instance, comprises a bracket 95 transversely disposed of the frame 1 and projecting a suitable distance therefrom and serving asa support for a pair of guides 96. Within these guides 96 is located a clamping jaw 97 having screw threaded engagement with a threaded rod 98, the latter being provided at one end with a right hand screw thread and at the other end with a left hand screw thread, whereby rotation of the saidrod 98 causes the two clamping jaws 97 to move toward or away from each other, causing in one direction of movement a releasing of the clamping action and in the opposite direction a clamping action. The action will readily be understood when it is explained that these jaw's 97 are brought into position between the legs of an adjacent machine and then moved outwardly to interlock with the frame of the adjacent machine. Rotation of the rod '98 is effected by means of a hand wheel 99 keyed or otherwise fixedly secured to the said feed member.

In Fig. 9 I have shown a modification which may be used in some instances at the delivery end of the machine, and preferably positioned adjacent thedischarge of the receptacle 57. This mechanism comprises a pair of conveyer belts 100 suitably mounted with one end of each in close proximity to the roll 6 and projecting over the discharge opening 101 of the receptacle 57, and from which position the twobelts diverge, thereby rolling the dough to form a longer loaf than would .be delivered from the'receptacle 57 without this said mechanism. These belts 100 are mounted for rotation on suitable rolls or drums 102 and 103, the former pair being rotatably carried by a shaft- 104 mounted on extensions 105 of the frame 1, and the latter suitably mounted in bearings 106 and driven by a chain of gears 107 from nates a bracket fixed to the front portion of the frame 1 and having a slot 113 therein within which the shaft 114 is adapted to seat y aforesaid shape. In this substantially cylinl drlcal shape 1t is ready for the molding and-be secured through the medium of a clamp member .115 operated by the handle 116. 3 This shaft 114 carries an idle sprocket 117 thereon which is adapted for engagement with the driving chain (not shown) by which the sprocketfi is driven in cases where the adjacent machine is utilized to furnish the driving-power. Movement of, the shaft 114 within the bracket 112. will cause the desired tension of the drivingchain as will be apparent. a

Before taking up the detailed explanation of the operation of the device,'attention is [directed tothe fact that when the machine isvused in its preferred form, that is, to form a Vienna loaf, the dough, before its delivery to my novel machine, has first been proved and molded into a substantially cylindrical,

shape which is formed by spirally rolling a sheet of dough and molding it into the 2 operation in the machine which I have dethe ends and and the machine is then connected through the medium of the clamping device 97 with o used in connection therewith, and so posiweight ofthe doughoverba ances the coun-- ght and causes thesaid plate 'to swing-- toward-the ends, thereby forming .an initial partially. formed dough to the second straightener-,- which point it is somefthree or longerthan when it entered the lation with 40.

' terwei vised for this purpose, and the'desired functionof which is to taper the dough from substantially the middle portion thereof toward produce the loaf known as Vienna.

The-operation of the "machine is as fol-.

lows :-The parts of the machineare first of,

course suitably adjusted with respect to each other in, order to produce the result desired an adjacent machine, provided one is to be tioned as to bring the conveyor mechanism and its i-receiving chute .34 into operative re the aforesaid machine. vWith the machine so arranged and the movie parts" receiving power,

are carried by the bolster or feed belt '17 upwardly alongthe inclinedbed 22 ge end thereof. At this point the dough cylinder-is discharged and confacts with the straightener late; 83 and the about its'pivot'and direct the dou h into the receptacle 37 and in contact withwthe face of the .rollll. The rotation of the sand roll 11 kneads or works the dough roll gradually drawing the'same from the center tapering shape and delivering the plate 83 at four inches receptacle. The action and function of this second plate 83' are exac tly similar to those described for the former plate, except at this time, owing to the double taperof the loaf,

the plate causes a slight curvature of the.

the quantitie'sfo l ,molded'doughare delivered one ata timeat suitable intervals into the chute 34,1fr0m which they 45 to the dischar longitudinal axis of the dough roll so that the same conforms substantially to the curvature of the roll 6 upon which it is deposited by the automatic swinging of the plate 83. The dou h roll now passes through the receptac e 57 and is further elongated,-worked and tapered so that when it is delivered u on the receiving table 81 it is'in the require form to bake into a Vienna loaf. If it is desired to form a loaf longer than the usual Vienna, the modification shown in Fig. 9 may be employed and it will readily be seen that the action ofthr dough T'e indepen ent means for adjusting each receptacle and each section of the receptacles is an important feature as thereb it is possible to var' to the desired extent the tapering or worhing action of the rolls and thus cause variations in the shape of l the finished product;

Attention is directed to the auxiliary frame 3 and'its pivotal action as thereby it is ossible to entirel remove both of the r01 5 6 and 11 from t e. forming receptacles in orderto permit the parts to be cleaned and scraped so that the machine may1 be maintained at all .times in good wor 'ng order. Of course it will be understood that any desired means for fastening or securingthe auxiliary frame in operative position may be employed, and for thispurpose I provide a lug 118thereon with which a pivoted latch 119 is adapted tovco ijperate.

In the makingo form the quantities of dough entirely by hand,- and in the commercial manufacture of this product the spirall rolled cylindrical quantities of dough are elivered to a traveling conveyer of sufiicient length to allow twenty or more then to stand on each slde thereof 'and the-dutiesof these men are to iremovethe formed rollsof dough and work Vienna loaves it has heretofore been the practice to mold and them up into tapered elongated forms ready forothe' bakingprocess.-

. In my present'inventionI-have devised a machine embodying structure adapted to stretch, mold and ta er, entirely automaticallm a cyllndrical r0 7 of dough's'o thatitfi-is delivered from the machine in a perfect-jsha f i 'for baking nto at Vienna loaf and w ereby the tedious ma complete unitary lengthy hand process heretofore'in vogue is dispensedwith. It will furthermore be apparent that in view of the fact that one roll of dough follows after another in rapid succession, the output of the machine is extremely large, rapid and the formation of each roll is accomplished in a minimum of features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in

the present instance, shown and described a' preferred embodiment thereof which has livering a predetermined been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
